Annotation Type Groovydoc

An annotation to hold the groovydoc for the annotated element at runtime, we call it "Runtime Groovydoc".
Runtime Groovydoc is a bit like Python's Documentation Strings and will be useful for IDE and developers who set a high value on documentations.
The usage is very simple, just place @ at the beginning of the content of groovydoc, i.e. starts with /**@,
then the new parser Parrot will attach the annotation Groovydoc automatically
